Caption: Cloning. Conceptual image depicting human cloning, showing an open capsule with embryos spilling out. Cloning is a process whereby an organism may be copied exactly by implanting its genetic material (Deoxyribonucleic acid, DNA) into eggs from the same species. It is theoretically possible to produce unlimited numbers of identical copies of a person. The image could also represent other concepts such as genetic experimentation or birth control.
